Consider two different flows over geometrically similar airfoil shapes, one airfoil being twice the size of the other. The flow over the smaller airfoil has freestream properties give by T[infinity] = 200K, rho[infinity] = 1.23kg/m3 , and U[infinity] = 100m/s. The flow over the larger airfoil is described by T[infinity] = 800K, rho[infinity] = 1.739kg/m3 , and U[infinity] = 200m/s. Assume that both µ (dynamic viscosity) and a (speed of sound) are proportional to T 1/2 . Are the two flows dynamically similar

energy can cross the boundaries of a closed system in the form of heat and mass

explanation:

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
